With a heavy deadline looming, the Nanotech team (myself and Nicolas Marechal) held an all night soldering/programming session. Chinese food and bottles of Becks made me feel like it was Wall Street in 1988.

The second part of our project (after the proximity sensors) was finished up and proven to be fully working. This functions much the same way as the proximity part but instead of proximity sensors, pressure pads are used. As someone moves on the pressure pad, more lights turn on and if no-one steps on it they drop down. There's only two of these though.

This is a brief breakdown of the proximity sensor stuff for the nano project for the Royal Academy of Engineering.

The proto-board (of which I hand soldered 4) which is used to control 3 1 watt LED's at a time.

The Arduino with it's beautiful wiring.

All 4 sets of 3 lights strung out and finished and working. Well not actually working, they're not plugged in.

The finished bits at the bottom, proto-board, Arduino and the little black guys on stalks are the proximity sensors.

The idea behind this is that the poximity sensors will trigger the three lights when someone gets close, there's four sets of these. Not only this but for super enviro-efficiency, the lighting systems are paired up for power. 6 lights, and 2 Arduinos run off one 12V 3.5A supply.
